  59  * We must interpret the quotes in the command line to rebuild the argv
  60  * array correctly:
  61  * - arguments are separated by spaces or tabs
  62  * - quotes serve as optional argument delimiters
  63  *   '"a b"'   -> 'a b'
  64  * - escaped quotes must be converted back to '"'
  65  *   '\"'      -> '"'
  66  * - an odd number of '\'s followed by '"' correspond to half that number
  67  *   of '\' followed by a '"' (extension of the above)
  68  *   '\\\"'    -> '\"'
  69  *   '\\\\\"'  -> '\\"'
  70  * - an even number of '\'s followed by a '"' correspond to half that number
  71  *   of '\', plus a regular quote serving as an argument delimiter (which
  72  *   means it does not appear in the result)
  73  *   'a\\"b c"'   -> 'a\b c'
  74  *   'a\\\\"b c"' -> 'a\\b c'
  75  * - '\' that are not followed by a '"' are copied literally
  76  *   'a\b'     -> 'a\b'
  77  *   'a\\b'    -> 'a\\b'
  78  *
  79  * Note:
  80  * '\t' == 0x0009
  81  * ' '  == 0x0020
  82  * '"'  == 0x0022
  83  * '\\' == 0x005c
